One-line lazy initialization

Is this too obscure?

public class MyObject
{
    private MyExpensiveObject _myExpensiveObject;

    public MyExpensiveObject ExpensiveObject
    {
        get { return _myExpensiveObject ??
                     (_myExpensiveObject = new MyExpensiveObject()); }
    }
}
